Answer:
Total amount at the end of week is 261
Step-by-step explanation:
Monique's savings account had a balance of $326.
She made a withdrawal each day till seven days = $45
So, Total withdrawal amount =
So, Amount left in saving's account=326-315=11
During that week, she also made two deposits of $125 each.
So, Total amount of deposit = 125+125=250
Let T be the balance in Monique's account at the end of the week
So, Total amount at the end of week T = 250+11=261
So,Total amount at the end of week is $261
For this case, the first thing we must do is define variables.
We have then:
t: number of hours
F (t): total charge
We write the function that models the problem:
Where,
b: represents an initial fee.
We must find the value of b.
For this, we use the following data:
Her total fee for a 4-hour job, for instance, is $ 32.
We have then:
From here, we clear the value of b:
Then, the function that models the problem is:
Answer:
the function's formula is:
Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
